SPECIFICATION forming part of Letters Patent No. 643,523, dated February13, 1900.

Application filed June 23, 1899. $erial No. 721,563. (No model.)

To all whom it may concern:

Be it known that I, CARL ADAM NEU- BEOKER,a subject of the Grand Duke ofHesse, residing at Offenbach on the Main, in the Grand Duchy of Hesse,Germany, have in- Vented certain new and useful Improvements inApparatus for Pitching the Internal Surfaces of Oasks, Barrels, or theLike, (for which I have applied for a patent in Germany, dated January9, 1899, and in Austria, dated May 29, 1899, No. 548,) of which thefollowingis a specification.

This invention relates to a device for carrying out the well-knownprocess of pitching the inside of barrels, butts, and store-casks insuch a manner that by injecting thereinto hot and fresh pitch the oldcoating of pitch is loosened and a new one laid on the inside of thebarrel. Devices for the carrying out of this object have been frequentlyproposed. The difficulties met with in the construction of these residein transferring pitch from the boilingpan onto the barrel in anappropriate manner. Hitherto pumps (piston and centrifugal pumps) havebeen proposed to introduce the boiling pitch into the barrels to bepitched. These mechanical devices present various disadvantages. Themoving parts get highly heated by the viscous hot mass and are subjectedto a rapid wear. Driving devices for these mechanical apparatus are as arule not i put down in the places where the pitching is efiected and aredifficult to construct. Lastly, the carrying out of the process is-forinstance, in the case of pumps worked by handnot without danger onaccount of the leaks that occur. These disadvantages are entirelyobviated by the present invention.

On the drawings, Figure 1 shows the new device in partial verticalsection. Fig. 2 is a top View of the boiling-pan. Fig. 3 shows athree-way cock and the pipes branching therefrom. Figs. 4:, 5, and 6representa modified form of the invention. Figs. 7 and 8 show a thirdmodification of the apparatus.

The new device is placed inside an open boiling-pan a of the usual kind.On the bottom of this pan a rests a short perforated cylinder b, whichis closed, for instance, by a conically-shaped partition 0, the openapex of which is turned downward. The latter is filled with a lightball-valve m or the like, by

means of which it can be closed. Above the said partition 0 rests acylinder (1, closed at the top and having such a capacity that itcontains a quantity of pitch sufficient to coat completely the inside ofa barrel. To the lid of. this cylinder is attached a pipe 6, which leadsto a three-Way cock f. A pipe g, extending from the under side of thelid down till it nearly reaches the aforesaid conical partition c, isrun to the cradle which supports the barrel to be pitched and carries atits upper extremity an injecting-nozzle. The boiling-pan a is fittedwith a coil h, connected to a pipe h and by the pipe b to the three-waycock f, to which is attached a pipe 2', communicating with theatmosphere. The pitch that runs out of the barrel his returned to thepan through the overflow l.

The mode of working of the device is as follows: The pipe h, attached tothe coil h, is connected to the compressed-air pipe, which is laid downin every brewery for the purpose of elevating beer by pressure. If thedevice is not in workthat is to say, if no barrel is being pitched-thethree-way cock occupies the position shown in Fig. 3, in which case thespace at the upper part of cylinder d is connected with the atmospherethrough pipe 6, cock f, and pipe 2'. In this case the pitch penetratesfrom the surrounding pan a through the perforated cylinder 17, raisesballvalve m, and fills cylinder (1 to such a height that the level ofthe liquid pitch is the same in pan 1) and cylinder (1. The pitch isthus kept liquid and boiling in the inside of cylinder d. The vaporsevolved can escape through pipe e and pipe 1' into the atmosphere.

When a barrel is to be coated internally with pitch, it is placed on thecradle, and the operator has nothing else to do but to turn thethree-way cock f from the position shown in Fig. 3 into that shown inFig. l. The compressed air that has been heated in coil h enters pipe hand passes through three-way cock f into cylinder cl. In consequence ofthe pressure exerted on the surface ofthe pitch in cylinder d ball-valvem closes the opening in the conical partition 0 and the pitch is pressedupward into pipe 9 and injected into the barrel. When the charge ofpitch in cylinder (1 has all been used up, no more will run back throughthe overflow Z int-o pan a. The operator can then bring three-way cock finto the position shown in Fig. 3, remove the cask that has beenpitched, and subject another one to a similar operation.

, The two modifications shown in Figs. 4 to 8 differ from the mode ofconstruction just described in having the pitch-boiling pan closed atthe top and the three-way cockf actuated by a pull-rod and bell-crank,one arm of which forms a pedal. The pipe 1', which connects the chargingvessel with the atmosphere, is connected to the chimney. The apparatusshown in Figs. 7 and 8 is intended for pitching two barrels at oneoperation. Besides this the compressed air is heated by means of asimple reservoir in lieu of a coiled pipe.

The largest barrels can be pitched by means of this device even if it isof small dimensions. As soon as the charge of cylinder d has been usedup the three-way cockfis turned around, the cylinder again filled up,and the second charge injected into the barrel.

Having thus described my said invention, I declare that what I claimis- 1. An apparatus for coating the interior of casks, the apparatuscomprising a pan, a cylinder situated in the pan and having a closedupper end, the lower portion of, the cylinder being perforate, a conicalpartition situated in the cylinder above the perforate portion thereof,a valve commanding the orifice in the apex of said partition, a pipeleading from the cylinder above the partition to conduct the material tothe cask, a second pipe in communication with the upper portion of thecylinder, a cock commanding said pipe and capable of throwing it intocommunication with the atmosphere, a third pipe connecting with acompressed-fluid source, the third pipe communicating with said cock andthe cock being capable of throwing it into communication with the secondpipe.

2. An apparatus for coating the interior of casks, the apparatuscomprising a pan, a cylinder situated in the pan and having a closedupper end, the lower portion of the cylinder having an orifice, apartition situated in the cylinder above the orifice thereof, a Valvecommanding an orifice in the partition, a pipe leading from the cylinderabove the partition to conduct the material to the cask, a second I CARLADAM NEUBECKER.
